2 Claims.

, This invention relates to a spinning centrifuge with a protective casing of special construction.

Spinning centrifuges are usually arranged in rows on the spinning machines, the revolving 5 spinning pots being surrounded by separate p'rotective casings, for protecting the other parts of the machine from being splashed by the acid. It has hitherto been the practice to fix these pro-' tective casings on the machine frame of the spinning machine. This interfered with the removal of the centrifuge. It was also necessary to mount the spinning case higher for enabling the motor to be removed after the removal of supports.

The invention overcomes this disadvantage by a separate protective casing which surrounds the spinning pot being fixed to a flange of the motor casing. In the lower part of the protective casing, at the inner periphery of the same, there is a collecting gutter provided with an outflow. The collecting gutter serves the purpose of catching the treating liquid which is thrown from the filament or out of the spinning pot and runs down the inside of the wall of the protective casing into the collecting gutter.

Furthermore, owing to the specially suitable shape of the motor casing, it is possible to dispose the place for the electric connections in the lower part of the motor casing. By this means the electric connection is established by simply placing the centrifuge on the base plate. A further effect of this arrangement is that the place of connection is shut off to the outside against detrimental chemical action. The electric switch for starting and stopping the motor is mounted directly on the casing.

Through all theparts of the centrifuge being combined to form a unit, the centrifuge can be erected independently. The entire construction is thus greatly simplified and its accessibility increased.

A constructional example of the invention is illustrated in the accompanying drawing in which Figure 1 shows a spinning centrifuge with a removable protective casing partly in section, and

Figure 2 a horizontal section on line 2-201! Figure 1.

The spinning centrifuge as a unit comprises an electric motor 6 which is mounted in a casing 1 and having a spinning pot 2 placed on the upper end of the vertically disposed shaft of the said motor 6. The motor casing 1 rests on a bed plate 4 with a packing layer 3 interposed between the two. The base plate 4 may be secured to a foundation in any suitable manner. The motor and spinning pot when mounted in this manner can easily be removed from the base plate 4 by mere- 1y lifting them as a unit.

Surrounding the spinning pot 2 is a cylindrical protective casing to conical or tapered. An inner annular tapered ermany August 11, 1930 member is attached to the lower end of the protective casing 10 and actsin conjunction with the tapered portion of the casing 10 to form a collecting or drainage gutter 11 for catching the thrown off liquid from the spinning pot 2 which liquid may then be drained through the pipe 12. This protective casing 10 is placed loosely over an upstanding annular flange 13 which is integral I with the motor casing 1. The casing 10 acts further as a protection against the spinning pot 2 being inadvertently touched by a worker or operative. A cover 14 fits over the top of the casing 10. In disassembling the casing 10 from the spinning unit, the cover 14 is first removed and then the spinning pot I lifted off and the protective casing 10 then taken off the flange 13.

In use the motor 6, spinning pot 2, and casing 10 can all be either removed from the base 4 together, or be replaced thereon as a unit. Provision is made in the base 4 whereby current to operate the electric motor 6 may be transmitted through the medium of upstanding pins 8 over which the sleeves 7 in the bottom of casing 1 slide, thus completing the electrical circuit. An electric switch 9 is mounted directly on the casing 1 for connecting and disconnecting the motor 6.

Having now particularly described and ascertained the nature of my invention and in what manner the same is to be performed, I declare that what I claim is:-

1. In a spinning centrifuge, a motor, a casing therefor provided at its upper end with an upstanding collar, a spinning pot located above said motor and operatively connected therewith, a protective casing for said pot having a tapered lower end, an annular tapered member attached to said lower end adapted to act in conjunction therewith as a collecting gutter, said annular member having a dependent flange for securing the said casing and said annular member to the said upstanding collar.

2. In a spinning centrifuge, a motor, a casing therefor provided at its upper end with an upstanding collar, a spinning pot located above said motor and operatively connected therewith, a

protective casing for said pot having a tapered l with an inner annular member whereby a collecting gutter is formed by the said tapered lower end and the inner annular member, and means attached to the said gutter for draining liquids therefrom.
